S 3005-G20Y vs Precipitation
S 3005-G20Y is a NCS color while Precipitation comes from PPG. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 40 and 41, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.9, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
S 3005-G20Y vs Precipitation in Real Spaces
2 real rooms side by side. S 3005-G20Y and Precipitation are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

S 3005-G20Y vs Precipitation Simulated Comparison
5 simulated room previews — drag the slider on each to see S 3005-G20Y on one side and Precipitation on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
